Hello Ronn,
Here's how I fit one of my lenses onto the small Speed Graphic board:
(there was a url link here which no longer exists)
As we have allready communcated by e-mail, these small boards take a bit of extra care, but they work well.
I also make a 135mm lens as an option to the 190mm lens.
Speed Graphic's bellows are a mite short, so the 135mm let's you get a bit closer than the 190mm.
As I mentioned elsewhere, I'll be out of circulation until mid-October.
More goodies on the drawing board.
Till then...
Reinhold
